## Homework Statement

The velocity of a wave of length L in deep water is v = K square root of (L/C + C/L)

where K and C are known positive constants. What is the length of the wave that gives the minimum velocity?

## Homework Equations

Possibly a(t) = v'(t) = s"(t)

## The Attempt at a Solution

I don't know how to work the question but here is my best guess...

Can I just cancel L with L and C with C (inside the square root) and be left with v = K.

Next, to find the length, can I just find the antiderivative of the velocity, like this: v(t) = Kt + C.

How do I workout this question?
